not to sure where to place this question but anyways. My fuel gauge on the stock cluster works but its kinda acting funky.

here are the problems:

when the tank is full the needle is past full by a lot (~1/2 inch maybe)

if the tank is empty the needle is on the bottom of the 1/8th mark right above E

if i fill my tank or close to full it the seems the gauge moves slowly but when the tank gets closer to empty the needle moves a lot faster.
**example: i drive 60 miles with a close to full tank. it'll show i used 1/8th of a tank. lets say i drive around and get to 3/4 of a tank the needle seems to go down way faster with the same driving.**

If i turn left/accelerate the needle moves toward full
If i turn right/deccelerate the needle moves toward empty

this isnt a big deal its just something i want fixed

Totally normal. See Shoebox's writeup:

wow that is honestly one of the dumbest engineering designs. GM could have changed the gauge so that it doesnt look like its all ****ed up

In 17 years of owning my Formula, it never became a problem. After working out basically the same table that Shoebox has of gauge postion vs. actual gallons remaining, I know exactly how much fuel is in the tank at any point in time.

No use in complaining about it now. Everyone deals with it.

yea same here but it just looks like its broken and doesnt look good. just a comestic issue to me

it took me the first time running out of gas to figure this out.

Similar situation with mine. When I picked it up, it was showing half a tank, so I stopped to top it off. Imagine my surprise when the gas pump showed 15 gallons when it stopped! I started looking for gas on the ground and a hole in the tank. To be fair, I think mine has an issue, as it's outside the ranges listed on Shoebox's site. I just haven't gotten around to testing the wiring yet.

yep same here. Second day drove the car to school thinking i would put gas in after cuzz the needle was right under the 8th mark and made it out of the parking lot and maybe 100 ft onto the made road with the closet gas station a mile away
